1003 Dual Envelope Generator

The Behringer 1003 is an authentic and meticulously engineered recreation of the classic 1003 dual envelope generator module from the legendary ARP 2500 modular synthesizer. This Eurorack module provides two independent, classic ADSR (Attack, Decay, Sustain, Release) envelope generators that are essential for shaping the dynamics of your sounds. Whether you are controlling the amplitude of a VCA to create distinct articulations, modulating the cutoff of a filter for expressive sweeps, or controlling the pitch of a VCO for dynamic effects, the 1003 provides the core modulation signals needed for a versatile and responsive modular system.

Each envelope generator in the 1003 module features a simple and intuitive layout with dedicated faders for each stage of the envelope: Attack, Decay, Sustain, and Release. The module accepts gate signals to trigger the envelopes, and also includes a manual gate button for hands-on triggering and testing of your patches. Both envelopes can be used independently to control different parts of your patch simultaneously. With its pure analog circuitry, the 1003 delivers the snappy, responsive envelopes that were a hallmark of the 2500 system, making it an indispensable tool for creating everything from sharp percussive hits to long, evolving pads.
